NIST 800-53 r5 controls that address this weakness (2)AI
| Control | Title | Family | Why it addresses this CWE |
|---|---|---|---|
CA-8 | Penetration Testing | CA | Penetration testing includes XML external entity payloads, detecting XXE vulnerabilities and enabling their mitigation. |
SI-4 | System Monitoring | SI | Identifies XML external entity processing via monitoring of unusual file/network access or resource usage. |
MITRE ATT&CK techniques this weakness enables
Our own two-way CWE↔ATT&CK cross-walk — a direct mapping with no public source (the CWE→CAPEC→ATT&CK chain leaves most top weaknesses, incl. XSS and SQLi, mapped to nothing). Drafted by Grok and spot-checked by Claude Opus 4.8.
Direction: ← other covers this;
→ this covers other (F/M/P = full / mostly /
partial).
